nvme-fabrics: introduce init command check for a queue that is not alive

Browse source

When the fabrics queue is not alive and fully functional, no commands
should be allowed to pass but connect (which moves the queue to a fully
functional state). Any other command should be failed, with either
temporary status BLK_STS_RESOUCE or permanent status BLK_STS_IOERR.

This is shared across all fabrics, hence move the check to fabrics
library.
